What are the signs of hazardous materials in our homes?

March 1st, 2023

When we buy or rent a house, we expect it to be a safe place to live. However, certain substances such as asbestos, mold, and pyrite may be present in our homes and cause health and safety issues. It is therefore important to know how to identify these substances to eliminate them. In this article, we will explore the signs that indicate the presence of asbestos, mold, and pyrite in our homes. We will also discuss how to deal with these substances to ensure a safe and healthy environment.


Asbestos is a material that was commonly used in the construction of homes before the 1990s. It can be found in insulation, ceilings, walls, floors, and roofs. Asbestos-containing materials can be friable and easily crumble, releasing invisible fibers into the air. If you suspect the presence of asbestos, look for materials that easily disintegrate or areas of the house that have been damaged. A test conducted by a professional can confirm the presence of asbestos.


Mold is another common problem in homes. It grows in humid environments and can be found on walls, ceilings, floors, and furniture. Signs of mold include black, green, or white stains on surfaces, musty odors, and respiratory or allergy problems. If you find mold in your home, eliminate the source of moisture, and carefully clean the affected surfaces. This may require plumbing repairs or ventilation modifications.


Pyrite is a mineral that is often found in basements. Pyrite is a common mineral composed of iron sulfide that tends to decompose and form sulfuric acid. This is why it is important to monitor its presence in building foundations to prevent the formation of cracks and swelling in concrete slabs, which can lead to significant structural damage and ground subsidence. In addition, particles from decomposition can contaminate air and water. Signs of pyrite include cracks in walls and floors, doors and windows that do not close properly, and sagging floors. If you suspect the presence of pyrite, testing and evaluation by a professional will be required.

In conclusion, it is crucial to detect the signs of hazardous materials in our homes as early as possible to preserve our health and that of our loved ones. The most common signs include strange odors, stains on walls or ceilings, gas emissions, and persistent health problems. If you suspect any of these signs, contact one of our qualified professionals at Qualitam to conduct tests and determine the presence of hazardous materials.
